Overview
The SN74LV4052ADYYR is a dual 4-channel CMOS analog multiplexer and demultiplexer from Texas Instruments, housed in a 16-pin SOT-23-THIN (DYY) package. It operates on a single supply voltage ranging from 1.65V to 5.5V. The device supports bidirectional transmission of both analog and digital signals with amplitudes up to 5.5V peak. Key electrical characteristics include an ON-state resistance (rON) typically between 22Ω and 180Ω depending on VCC, and extremely low input current consumption. It features high ESD protection ratings of ±4000V for the human-body model and ±2000V for the charged-device model. The component functions within an ambient temperature range of -40°C to +125°C.
Feature Summary
- Dual independent 4:1 analog switching architecture controlled by shared logic inputs A, B, and an active-low Inhibit (INH) pin.
- Capable of handling mixed-mode voltage signals, allowing simultaneous transmission of analog and digital data across channels.
- Provides robust electrostatic discharge protection exceeding JESD 22 standards for reliable operation in sensitive environments.
- Maintains low crosstalk between switches and high off-state isolation to ensure signal integrity during multiplexing operations.
Applications
- Telecommunications systems requiring signal routing and channel selection.
- Infotainment units utilizing signal gating and isolation for audio/video paths.
- I2C bus multiplexing applications connecting multiple slave devices to a microcontroller.
- Home appliances employing programmable logic circuits for sensor signal management.
- Modulation and demodulation processes in communication hardware.
Procurement Notes
Verify the specific DYY package suffix against the latest TI orderable part number list to confirm availability status. Ensure the selected variant matches the required operating temperature range and material specifications for your manufacturing process.
Selection Notes
Select this component when space-constrained designs require a compact SOT-23-THIN footprint for dual 4-channel switching. Confirm that the system supply voltage falls within the 1.65V to 5.5V range and that the signal amplitude does not exceed the 5.5V peak limit. Evaluate thermal performance if operating near the upper temperature limits.
Part Context
This device belongs to the SNx4LV4052A family of dual analog multiplexers. It shares functional compatibility with other packages like SOIC (D), TSSOP (PW), and VQFN (RGY), offering design flexibility while maintaining identical electrical performance across form factors.
Replacement Considerations
Direct replacements include SN74LV4052ADBR (SSOP) or SN74LV4052ADR (SOIC). Verify pinout compatibility and physical dimensions before substitution, as the DYY package differs significantly in size and lead configuration from standard SOP variants.
